| Many normal conducting magnets were used in IMP accelerator's magnet system. The magnet design, fabrication and measurement of CSR are presented. All magnets will be laminated and welded with 0.5mm-thick steel sheets. The dipole of CSRm was chosen an H type with an air circle on the pole and CSRe was chosen the C type with an air circle and two air slots on the pole to improve the field homogeneity. CSRm and CSRe quadrupoles diameter is 170 mm and 240 mm and has two different lengths. All quadrupoles' endplates were also made with punching pieces after coating epoxy glue, there is also chamfered directly on the pole ends to reduce 12th order contribution of field and without the remounted pole end. Some superconducting magnets research at IMP will be reported too. A super-ferric dipole prototype of FAIR Super-FRS is being built and tested. This super-ferric dipole static and ramping magnetic field was measured in IMP; it reaches to the design requirement. A 3 T superconducting solenoid with a 70 mm warm bore has been developed to calibrate Hall sensor, some testing results is reported. And a penning trap system is now being developed for precise mass measurements. | ||
